fix: validate keywords first in update() for correct error reporting Check unknown keywords before arg parsing in all 4 update() functions. Fixes cases where update(b'a', extra=1) reported wrong error. Also reject unknown keywords in tp_init via shared _check_kwargs helper.

fix: tp_init accept 2 positional args and keyword data for PyPy PyPy doesn't support tp_vectorcall, so tp_init is the only constructor path. Accept up to 2 positional args (data, seed) and keyword data= and seed=, with duplicate detection for both.

feat: support data= keyword in update(), matching hashlib Change update() from METH_O to METH_FASTCALL|METH_KEYWORDS, accepting both positional and data= keyword argument. Matches hashlib's update(data=None) behavior.

fix: raise hashlib-compatible error for None input Add Py_None check in _get_buffer_or_str to raise: TypeError: object supporting the buffer API required matching hashlib.md5(None) exactly. Tests updated to verify.

test: add keyword str rejection tests for all entry points Test that data='hello' (keyword) raises the same 'Strings must be encoded before hashing' error as positional str for one-shot functions, constructors, and update().
